APPLICATION FILED JUNE 3, 1912.

Patented May 20, 1913.

R o T N E V m PATENTOFFICE i rrroMAsr. PAYNE,- or PITTSBURGH, :PENNsYLvANIAQ To all whom it may cohcem I Be'it known that I, THOMAS F; PAYNE, a

siding at Pittsb'urgh, in the county'of Al- "leghen'v and State of Pennsylvania, a citizen. of the; United States, have invented or discovered certainnew and useful Improvements in F rost-Proof Water-Closet Valves,

My inventlon relates to the construction of'frost-proof water closet valves; and the "object of myinventionis to provide a valve 'c onstruction wherein the- -po'ssibility of its freezing, and thereby being rendered mopcotiperates wit-h the inner surface of the I'll? erative, 'Will be reduced to a minimum.

- A further object of my invention isto provide a valve throughv which water mayflowfreely during the flushing operation.

A still further obj ect'ofmy invention is to provide a valve, which,""-in addition to having'the above characteristics, may be easily taken ap'artgfor adjustment or-repairs.

In the accompanying drawing, wh ch forms part of my specification, I have illus- I 1 This drawing is avertical sectional ;view of trated the preferred formiof my invention.

the complete valve construction.

Irithe construction shown herein a casing I 1 isjprovided, atits lower end, withva water ,inlet 2 and a drain outlet 3; and, at itsfu p per end, 'with an orifice4, whereby connec- 'tion is made to a reservoir (not shown) and a flushing pipe 5, which'may be connected to a water-closet bowl; Within the casing 1 there 'is mounted a reciprocating rod "6, pro- 'videdwith a' series of valve members,'-and havingoperative connection to a closet-se t" 7. The general arrangement of'these parts is such that the user, as he occupies the seat, depresses-it and lifts the rod6, so that water flows from a supply pipe through the reservoir WllljfiOW through the'fiushing pipe 5 and be efi'ective to flush the closet bowl connected to such pipe.

. The casing, as particularly shown:- herein,

consists of a bottom T-member 8, a p1pe-.

section" 9, a top .T-member 10, ahd a cap 11. The bottom T-member is rovided with the lateral water-inlet 2 and. e drain outlet 3,

1 and is threaded'to receive the pipe section-f- 1 9. The inlet-2 fopens into a chamber 12, whieh,--when the rod 6' is inits lowermost position, is closed at each end by valve forming, with the wallofthe said chamber, EtplStdIl valve, and the valve-meniber 14 be- Speci'fication of Letters fatent.

, f members 13 and 14, carried by the said rod' -6; the valve-member 13 being a cup-washer V ing a seatvalve adapted to bear against an upwardly extending flange 15. 'At the bot:

tomof the trough 16, formed by the wall of the T-member 8 and the flange 15, there is an inlet to a by-pass 17,, which by-pa'ss extends to the lower side of the cup-washer i 13. In order to shut oil the escape through the by-pass- 17' of water from the casing above the valve 14, the rodffi is provided with a piston valve '18, which to such end,

19 when the rod is in lifted position.

will be seen of this construction-that, when the rod 6 is in, the position indicated in the drawing, and the flushing of the closet bowl has been, accomplished, all the water in the pipe-section 1, above the valve 14 will escape through the by-pass 17 to the drain Such a construction is particuout-let larly advantageous in that theonlybodyof water in contact with the valve rod'6, which water, if it should freeze, would render the entire construction inoperative, is the 'Wa 1 ter in the chamber12. The water in this chamber is under pressure'and therefore freezable'ata lowertemp'erature than water under normal atmospheric pressure. I

The T-member 10 in'which the orifice l is located is suitably {.threaded'to receive 'the pi'pe-section 9- at its lower end and the cap 11; at its upper end. The rodfi, which extends -.through the T-member 10', as well as the cap 11, is held yieldingly in its dow'nward'positi'on bya spring 20, which bears at o ne endagainst the shoulder 21 ,of t'he said rod and at the other end against a springdepressor such .as the skeletoncage 22, which cage in turn bears against the cap 11, surrounding the said rod. The said cap has a horizontal port-provided partition.

23, adapted to be, closed b the valve-seat 24;,carried'by therod 6; an a boss25, havin'g -anlo'utwardly beveled edge, is adjacent to the port opening on the lower side of the partition. By such an arrangement of parts'in the T-memb'er 10, the spring 20 may, as shown,'be coiled closely to the rod S'thereby reducing to a minimum the space which. such spring occupies, and giving. a

freepassageway to the flow of water through the pipe 1 and -T-member 10. When the rod. 61s raised, as heretofore described, the a valve-seat 24 will close the port in the partition 23 and the water (flowing through the inlet 2, chamber 12, open valve 14 and pipe 9) will flow through the orifice 4 into a reservoir. After the rod is lowered the valve 24 will be unseated and the water will flow freely through the skeleton cage 22, flushing pipe 5 and ports 28. By beveling the boss so that its lower edge forms a ring of' larger diameter than that of the valve seat 24, it will be seen that water draining from the flushing-pipe 5, will follow the beveled edge of such boss and fall outside of the valve seat 24, so that it will not freeze thereon.

The rod 6 extends through the cap 11 and a suitable quantity of packing 34 is held in position around the rod by a nut 26. The flushing-pipe 5,-which is secured to the cap 11 by means of a union 27, is closed at its outer end and provided with a plurality of radiall arranged ports28, and the bottom of the sai pipe is sloped downwardly from-the outer end so that water will not bein the end thereof and freeze. A pair of arms 29, formed integrally with the flushing-pipe .5

afiordsa pivot point for the seat 7, which' is pivoted in the arms'29 by a hinge member 30having a-finger 31 adapted to extend through .a slot 32 in the .top of the rod 6, a'set' screw .33 being provided at the top of the rod whereby the extent of the reciprocation of the rod may be determined.

The full operation of the valve will be apparent from the foregoing description. It will be observed that, by disconnecting the cap 11 from the T-member 10, and from In a frost proof water-closet valve, the 4 combination of a casing having a water inlet, a dlscharge outlet, and a reservolr connection between said inlet and outlet, a fixed v valve seat within said casing between said outlet and said connection, a movable valve rod extending through said casing and provided with a valve closure cooperating with said valve seat, and a compression spring below said valve seat surrounding said rod and yieldingly holding said valve closure in open position, the lower end of said spring operatively engaging said valve rod and the upper end thereof exerting its pressure against the lower side of said valve seat.

2. In a frost-proof water-closet valve, the combination of a casing provided at its lower end with a water inlet and a. drain orifice, and at its upper end with a discharge .outlet and a reservoir connection, a capforming the upper part of the said casing and provided with a valve seat, a valve rod' extending through the said casing and held yieldinglyin its downward position by. a spring engagingat its lower endthe said rod, and a skeleton cage extending from the under side of the capvalve s'e'at to theupper end of the said spring.
